SPECIFICATION forming part of Letters Patent No. 423,507, dated March18, 1890i Application tiled May 21,1889.I Serial No. 311,571. (Nomodel.)

To all whoml it may concern:

Be it known that I, MCCLIN'rocK YOUNG,

of Frederick, in the county of Frederick and State of Maryland, haveinvented certain Improvements in Brush-Machines, of which the followingis a specification.

This invention relates to a machine intended to facilitate theseparation of bristles into tufts, the folding or doubling of thesetufts, and finally their insertion intoholes or seats in thebrush-block. v

In the accompanying drawings, Figure l is afront elevation of a machinecontaining my improvements. Fig. 2 is a perspective view of thebristle-support. Fig. l is a horizontal cross-section through thebristle-dividing ing serting-blades.

Fig. 3 is a side elevation of the machine. Figs. V4, 5, and 6 arecrosssections on the line r zo, Fig. 1, showing the -successive steps inthe formation and introduce,

`tion of the tufts. Fig. 7 is a side View, partly y in section, showingthe manner in which the layer of bristles is divided into tufts.- Fig. 8is a similar View showing the manner in which the tufts are carrieddownward betweenthe dividing-teeth into the block.

by hand or otherwise, step by step, in order to bring the successiverows of tuft-holes be- 'llhe table may thereto,vas shown, in order toadmit of its inclination being changed when tufts areto be inserted intoinclined holes. The manner of attaching this table forms no part of thepresent invention.

D represents a fixed bristle-support bolted to the frame. It is in theform of a horizontal plate, one end of which is extended to the rightand turned upward in order to receive and hold a supply of bristles,while the other end is extended horizontally over the position occupiedby the brush-block. The end which overlies t.he"brushblock is providedwith a vertical slot d, extending in a direction transverse to theblock. It is also providedwith a horizontal finger d', lying slightlyabove and parallel with the surface of the plateand susn,

tained wholly at the upper or elevated end, so that the bristles may bepassed thereunder from the right in such manner as to lie across theslot d in a sheet or layer. A gage bar or guide d2 extends along therear edge of the plate, and is secured by bolts, d3, passing throughslots, so that it may be adjusted forward and backward. The bristles arecut to a uniform length and presented at the rear end against the gagewhich serves to control their longitudinal adjustment, so that they willalways extend equal distances on opposite sides of the slot'.

The inserting devices are located directly above the support D. Theyconsist, essentially, of two vertically vand independently movableblades E and F, each provided with a series of downwardly-extendingteeth at the lower end. pointed to pass through the layer of bristlesupon `the plate Dand divide the same into bunches or tufts, as shown inFigs. 4 and 7. The blade F has its teeth notched or. indented atthe endand located opposite the spaces between the teeth of blade E. After thelayer l their length, driving them down through the.

slot d. The tufts are by this action doubled or folded over the teeth,which continue their descent unt-il they carry the tufts deeply to theirplaces `in the holes of the brush-block, as shown in Fig. 6.

The dividing-blade E descends only until its teeth rest upon the uppersurface of the brush-block between the tutt-holes, as shown in Figs. 6and 8, when it remains at rest, so

- that its fingers servev thereafter as vertical guides to assist inconfining and directing the tufts as they are carried downward betweenthem by the teeth ofl the inserting-blade.

This machine is intended only to seat the tufts in place. They may besecured tl1ere after by transverse wires, applied as shown in myapplication, Serial No. 280,502, dated July 20, 1888, or in any othersuitable manner.

The dividing and inserting blades E and vF may be mounted and operatedin any appro priate manner;-but I recommend for this pur- IOO pose thearrangement represented in the drawings, in which the driving-blade F issecured rigidly to a vertical slide G, mounted in guides in the mainframe and connected by a link g to crank-arms g on a horizontalrock-shaft g2, lthis shaft being 'mounted in bearings g3 in the frameand provided at one end with a hand-lever g4. k'Ihe plate E is mountedto slide vertically in suitable guides on the face of the blade F, asshown in Fig. l, and connected by a link e to one end of a lever e',which is pivoted at the middle tothe blade F or its carrying-slide,andarranged at the opposite end to encounter a stationary stop e2 when theparts are elevated. A spring e3 urges the blade E constantly downward inrelation to the blade F. When the parts are v in their normal elevatedposition the blade F stands above the blade E, as shown. When the slideG is lowered by the hand-lever, the

' lever e is carried' away from the stop and the spring e3 permitted todrive the fingers of the blade F downward through the layerof bristlesand downward through the slot in the supporting-plate until the ends ofthe teeth rest upon the face of thek block. The blade F, followingdownward, acts within the tufts and, overcoming the blade E,passesbeyond the same, forcing the tufts to their seats.

The essence of my invention' resides in the combination of two toothedblades-one adapted to divide the bristles into tufts and the other toforce these tufts into the block.

As regards the support D the only requirement is, that it shall beadapted to sustain y the bristles in a sheet or layer, and that it shallhave a'slot or opening through which the blade may pass, and by whichthe bristles shall be divided or folded over the ends of the blades. Y

kI do not claim herein the dividing-blade E or the separation of theseblades broadly with a slotted support for the bristles.l Neither do Iclaim herein the special arrangement of devices for imparting thedifferential` motion to two blades, the same being the subject-matter ofa separate application, Serial No. 311,572,

filed May 2l, 1889.

Neither do I `claim herein the table ypivoted to the frame, as hereinshown, the same being also claimed in the above-mentioned application.

'While I have represented herein4 a sta- 2 I. v y423,507'

tionary support for the bristles, it is to be distinctly understood thatthe two toothed blades herein shown may be used in combi'- nation withany suitable automatic mechanism for feeding the tufts of bristles.

Having thus described my invention, what I claim is l. In a machine forforming and inserting tufts, the combination of a slottedbristlesupport, a blade movable through said slotv from above, a slottedbristlefsupport prov vided with a fixed overlying finger d to confinethe bristles in position 4. In a brush-machine, the bristle-supportupturned end, the vertical slot at the opposite end, and the overhangingfinger d to confine the bristles in position across the slot.'

5.v` In a brush-machine, in combination with.

a bristle-support having an opening through which the bristles may befolded and delivered, a reciprocating blade having teeth to vdivide thebristles and an independentlymovable reciprocating blade havingtuftdriving teeth intermediate of the teeth of the first-named blade. ni

6. In a brush-making machine, in combination with a suitablebristle'support, a reciprocating blade with pointed teeth to-divide andunite the bristles, and a second and in.- dependently movable blade withtuft driving teeth, the ends of which are indented to straddle the tuftswithin their bight or fold. In testimony whereof I hereunto set my hand,this 10th day of May, 1889, in the pres*-v ence of two attestingwitnesses.
